REENFORCED METALLIC LINING.

T 0 all whom it may concern:

Be it known that I, JoHN A. MACKENZIE, a citizen of the United States,residing in the city of' Alameda, in the county of Alameda and State ofCalifornia, have invented a new and useful Improvement in a ReenforcedMetallic Lining, of which the followin is a specification. I

y invention relates to improvement in reenforced metallic liningswherein a metallic reticulum imbedded within a sheet of lead operates inconjunction with flanged washers arranged at regular intervals withinthe interstices of said reticulum to detachably retain said liningagainst a surface.

The present state of the art discloses a metallic lining permanentlyattached to the interior surfaces of evaporators and containers for theproduction of acids and the like, said lining being held to such surfaceby means of a metallic reticulum permanently attached to said surface bymeans of rivets or other permanent devices, said lining being flowed orcast, while in a fluid or melted state, through the interstices of thereticulum thereby requiring that such lining be applied to the containerwhile in course of construction and within a shop having facilities forsuch application.

Some containers are too large to be constructed within the shop and insuch cases the material of said container is shipped to the requiredlocation and there assembled. T0 line such containers with the meansdisclosed in the present state of the art would require the erection ofa shop and transportation of suitable mechanism to make suchapplications.

The primary object of the present inven tion is to provide an improvedreenforced metallic lining of the character described adapted forerection or application in the field or remote from the shop.

A further object of the present invention is to provide improved meansfor detachably securing the lining to a surface whereby said lining maybe detached afterthe container has outlived its usefulness and reappliedto another container or the like.

A still further object of the invention is to provide an improved liningof the type set forth wherein the supporting reticulum may be morecentrally imbedded within the lining to more efficiently support theweight thereof, and thereby provide superior en- Specification ofLearsratent.

gagement and to increase facilities for preventing creeping ordetachment of. the lining.

A further object is to provide improved means for positioning theapertures in the bonding element to register with apertures in the rigidsurface to which the lining is to be applied. 3

A still further object of the present invention is toprovide improvedmeans for lining containers and the like without the expensive processof previously tinning the surface or plate to which it is to beattached.

I accomplish these and other objects by means of the improved devicedisclosed in the drawings forming a part of the present specificationwherein like characters of reference are used to designate similar partsthroughout the said specification and drawings, and in which- Fig. 1 isbroken elevation of my improved lining partly broken away to disclosethe supporting reticulum and the bonding means for securing the same toa surface;

Fig. 2 is a broken view of a section of the reticulum and the bondingmeans;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2 in the directionindicated;

Fig. 4 is a sectional view of the lining as applied to a metal plate;

Fig. 5 is an enlarged elevation of a modified form of bonding washer;and

Fig. 6 is a sectional View of Fig. 5.

Referring to the drawings the numeral 1 is used to designate a sheet oflead or other suitable metal impervious to the action of acids andhaving regularly spaced apertures 2 therein, within which is imbedded ametallic reticulum 3 having certain interstices registering or alignedwith said apertures 2 of the sheet of lead 1.

WVithin such registering or aligned interstices of said reticulum 3 arethe bonding means or washers 4 having a flange 6 around the edges of oneside thereof.

The flanged side of the. washers 4 are imbedded within the sheet of lead1 while the opposite side of said washers 4 are arranged flush with theside of said sheet 1 thereby providing a bonding means adapted to berigidly and detachably secured to a surface without pressure upon saidlining.

The washers 4 are also provided with centrally disposed countersunkapertures 7 through which are inserted rivets 8 or other I sheet of lead1, reticulum 3 and washers 4 are fabricated in the shop and transportedto the field of operations. The linin is placed in position so that theapertures of the washers 1 register with the apertures 11 in the plate 9to be covered or lined and the rivets 8 are then'passed through theregistering apertures 7 of-the washers 4 and the apertures 11 oftheplate 9 and suitably secured.

As the washers are provided at regular intervals within the intersticesof the reticulum 3 it is obvious that a uniform adherence will beprovided to efiectively and efficiently retain the lining to the metalplate 9.

It sometimes happens that the lining is slightly distorted duringtransportation thereby throwing the apertures 7 of the Washers l out ofalignment with the apertures 11 of the plate 9. In order to properlyreposition the apertures 7 I have provided the modified form of washer 4Having concentric nested washers 12 and 14 rotatably mounted therein.

By means of this novel arrangement the apertures 7 may be repositionedto align or register with the apertures 11 in the plate 9.

The washers 4 are also provided with the same flanges 6 in order toeffectively engage the inner side of the reticulum 3.

After the rivets 8 have been properly secured the apertures 2 in thesheet of lead 1 are filled with lead discs 16 and the adjacent edges ofsaid disc 16 and the apertures 2 are melted and fused by the applicationof heat in such a manner as to fully cover the rivet heads and therebyprevent exposure of same to the action of any acids which may come incontact with the lining.

Thejunction of the sections of the linings are filled with a strip oflead 17 to which heat is also applied to fuse the adjoining edges ofadjacent plates, thereby efiectively combining the several sections toform a unit and effectively line the entire structure.

It isobvious from the foregoing that I have provided an improvedreenforced lining having improved means for effectively supporting thesame to the surface of a container or the like, whereby said plates maybe removed when the container or plate to .too large to be constructedwithin the shop and later transported to the desired location.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is-- 1. A reenforced metallic linin comprisinga sheet 01 lead; a metallic reticulum imbedded within the lead; andwashers mounted within the interstices of the reticulum and within thelead end flush with one side thereof to detachably connect saidreticulum and lead to a surface.

2. A reenforced metallic lining comprising a sheet of lead; a metallicreticulum imbedded Within the lead; and flanged Washers mounted atregular intervals within the interstices of'the reticulum and having oneside thereof arranged flush with one side of the sheet of lead wherebysaid lining may be detachably connected to a surface, said flanges onthe washer engaging the reticulum to hold the same and the lead rigidlyagainst said surface.

3. A reenforced metallic lining comprisin a sheet of lead; a metallicreticulum im edded within the lead; and apertured flanged washersmounted at regular intervals within the interstices ofthe reticulum andhaving one side thereof arranged flush with one side of said sheet oflead, said flanges operating to engage the reticulum and hold the sameand the lead against a surface; and means for engaging the apertureswithin said washers and for retaining said washers and the reticulum'and sheet of lead against a surface.

4:. A reenforced metallic lining comprising an apertured sheet of leadametallic reticulum imbedded within the sheet of lead and having certaininterstices registering with the apertures in said sheet; aperturedflanged washers mounted within such registering interstices of thereticulum and having one side thereof arranged flush with one side ofthe sheet of lead and the flanges engaging the far side of the reticulumimbedded therein; and means for engaging the apertures within thewashers and for holding the flush sides thereof against a surface towhich the lining is to be attached whereby said flanges on said washersmay engage and retain the reticulum and sheet of lead against suchsurface.

In witness whereof I hereunto set my signature.

JOHN A. MACKENZIE.
